Window Service - Double Glazing

I was given Nathan's phone number when I desperately needed someone to fix my French balcony doors. They were only 3 years old and didn't drain properly. If it was raining for more than 2 hours I could be sure I would have water in my living room. Nathan was able to fit me in his schedule very quickly and when he came he was able to fix everything. He checks what needs to be done and then tells how much it would cost. And not only he fix the drainage (apparently the window frame was sealed and the weeping holes led nowhere outside) but also readjusted the doors so I can finally close them without using excessive force (and they are finally quiet too). I also shown him the studio windows which I wasn't sure if I wouldn't need to change completely, and he was able to fix these as well, without even charging additionally for extra 30 minutes of work. We are very happy that we got his details, it keeps raining all the time now and everything is dry. Finally!
